Oil prices slide as US stockpiles grow

Oil prices plunged after a report showed stockpiles of crude oil soared last week.

The inventory spiked by 9.4 million barrels, about triple what analysts expected. The build-up comes as oil prices have rallied in recent weeks, leading to higher prices at the pump. But analysts said that could change, since there’s still a massive oversupply.
